In some cases, appendicitis can lead to the development of a lump on the appendix called an appendix mass.
If an appendix mass is found during an examination, your doctors may decide it's not necessary to operate immediately.
Instead, you'll be given a course of antibiotics and an appointment will be made for an appendectomy a few weeks later, when the mass has settled.
Another possible alternative to immediate surgery is the use of antibiotics to treat appendicitis.
